摘要

A study of the aeromagnetic data from Wadi Qena’s central area was conducted to assess the depth of the basement and identify structural trends that could affect groundwater occurrence. To identify the edges and/or contacts of the magnetic source, various edge detection techniques were employed, including the first vertical derivative (FVD), tilt angle derivative (TDR), and Euler deconvolution (ED). Conversely, the depth of the basement was assessed through a variety of methods, including analysis of the power spectrum (APS), analytic signal (AS), source parameter imaging (SPI), and 2D magnetic modeling. The study highlights that two primary regional trend systems structurally govern the configurations of the basement. The first trend pertains to the Gulf of Aqaba and is primarily oriented in the NE-SW and NNE-SSW directions. The second trend pertains to the Gulf of Suez and Red Sea trend, primarily oriented in the NW-SE and NNW-SSE directions. According to the AS technique, the depth of the magnetic source varies from 225 m to 2726 m. The estimated depth derived from SPI ranges from 322 m to 2628 m. The average depth calculated with SPI and AS is approximately 1475 m. The 2D modeling of magnetic data reveals that the basement is cut by several faults, which impact the topography of the basement and the thickness of the sedimentary cover. The southwestern area, as indicated by the outcomes of AS, SPI, and 2D modeling, exhibits deeper basement relief that could serve as an ideal site for groundwater accumulation.
